Using Aerocore construction featuring Koroyd and Smith’s innovative Exoskeleton design to provide increased protection in side-impact zones, this is the helmet for athletes pushing the limits on the mountain. The Wayfinder Strap System featuring Fidlock is functional simplicity, making it easy to use one hand for on and off buckle use. For the most custom fit, the Quantum offers the Boa 360 fit system with a 360˚ halo design. Combine all this with the Smith-pioneered AirEvac technology for superior goggle integration. The Quantum delivers maximum protection and functionality for use in the most critical situations.
